Materials scientists have decided to define, rather than measure, Avogadro's constant, triggering a lengthy debate over what number to choose. Now one physicist thinks he has the answer.
Particles of dark matter should trigger nanoexplosions in certain materials, an idea that could lead to an entirely new generation of detectors, say physicists.
Inks made from different types of materials, precisely applied, are greatly expanding the kinds of things that can be printed.
Tiny robots that work together like ants could lead to a new way to manufacture complex structures and electronics.
A flexible electronic skin patch has strain gauges to measure tremors, and heating elements to release drugs held inside nanoparticles.
A simple way to carve patterns onto nanodiamonds without damaging them could lead to a new generation of photonic devices, say materials scientists.
An exotic form of carbon could help relieve a growing problem with the copper used in computer processors.
Tailor-made medical devices could give a more detailed picture of cardiac health and may be better at predicting and preventing problems.
Physicists have long known that entangled photons can make more precise measurements than independent ones. Now Japanese physicists have built a microscope that proves it.
A new wrinkle in the control of waves.
